Disclosed is a method of providing information for the deaf. The information providing method for the hearing impaired includes the steps of: a controller receiving a sound including noise and converting the received sound into a voice signal including the noise, and the controller converting the converted sound signal according to a signal-to-noise ratio of the converted voice signal Generating the noise-free voice signal by removing the noise from the generated voice signal, generating a voltage according to the noise-free voice signal by the controller, and the controller converting the voltage to a plurality of haptic feedback modules Applying, and generating various vibration patterns by the actuators of the plurality of haptic feedback modules according to the amplitude or frequency of the applied voltage, and generating the noise-free speech signal by the controller Dividing the converted speech signal into N (N is a natural number) frames, the controller performing Fourier transformation on the speech signal divided into the N frames, the controller performing a Fourier transformation on each of the N frames Calculating the spectrum of the converted speech signal and the spectrum of the noise signal, the controller dividing the spectrum of the converted speech signal and the spectrum of the noise signal into four frequency bands, the controller into the four frequency bands Calculating a signal-to-noise ratio for each of the divided spectrums of the converted speech signal, the controller setting each coefficient value according to the calculated signal-to-noise ratio, and the controller for each spectrum of the noise signal Calculating each product value by multiplying each coefficient value calculated according to the signal-to-noise ratio, and the controller subtracts each product value from each of the spectrums of the speech signal to obtain the noise. Calculating a signal from which the signal has been removed, merging the spectra of the signal from wh
